SWINGING DISPLAY-LEAVES.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed April 25, 1908. Serial No. 429,140.

To all whom it may concern:

Be it known that I, ALFRED M. PARKS, of Philadelphia, in the county ofIhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Swinging Display-Leaves, whereof the following isa specification, reference being had to the accompanying drawings.

My invention relates to a substantial and durable display device forcarrying swinging leaves, such as may be used for displaying railroadtime-tables, telephone indexes, notices or other similar objects inpublic places.

One object of my invention is to so construct the leaves as tothoroughly protect the displayed object from injury or wrongful removal.

Another object of my invention is to facilitate the ready removal of anyone leaf by a person authorized to do so, without disturbance of theothers.

Another object is to so construct and mount the leaves as to permit theremoval of the cards or other displayed objects from the leaves, as soonas the leaf is detached from the stand, but to make such removalimpossible while the leaf is in lace.

Other useful features of t e invention will be referred to in thespecification.

In the accompanying drawings, Figure I, is a plan view, and Fig. II, isa front elevation of a display stand embodying my invention. Fig. III,is a central vertical section along the line III, III, of Fig. I. Fig.IV, is a central horizontal section on an enlarged scale of a singledisplay leaf taken along the line IV, IV, of Fig. III. Fig. V, is adetail as hereinafter explained.

As thus illustrated, the device includes a permanent back-board 1,provided with a lower ledge 2, and an upper ledge 3. These parts mayconveniently be made of wood, and may be properly ornamented. The lowerledge 2, is provided with a series of pivot or socket holes 4, which actas thrust bearings to receive the lower ends of the pivotal supports forthe leaves. The upper ledge 3, is similarly provided with acorresponding set of a ertures 5, for the reception of the upper encs ofthe pivotal bearings. These apertures are of peculiar shape, asillustrated in Fig. V, in that the circular aperture 5, is a verticalone, extending directly through the ledge, and of a size suitable toreceive one of the ivotal bearings, but provided with a beve edenlargement 7, on the under side, and a corresponding oppositelyinclined beveled enlargement 8, on the upper side, whereby when apivotal bearing is to be removed, its lower end after being unseated,may be drawn forward a sufficient distance to clear the lower ledgewithout bending the upper end within its receiving aperture.

For the purpose of simultaneously looking all of the swinging leaves inplace, a locking shelf 10, is provided, which is hinged to the back at11, and which, when swung to its horizontal position, rests upon the topof all of the pivotal bearings, preventing them from being suflicientlyraised through the ledge 3, to allow the lower bearing pivot to beunseated from its socket. In order to secure this locking shelf againstunauthorized interference, a lock 12, is provided, the bolt of whichengages a staple-shaped keeper 13, fast to the ledge 3, so that only onepro-= vided with the key to this look can render the shelf capable ofswinging up sufficiently to permit the removal of the leaves from theirbearings in the ledges.

Each leaf consists of a light but strong framework, 20, preferablyrectangular, and provided with interior strengthening rods 21. The innervertical edge of this frame work is prolonged in a downward direction toform the bearing pivot 22, and in an upward direction to form thelocking pivot 23 the vertical height of the leaf being suificiently lessthan the distance between the ledges 2, and 3, to permit the leaf to beraised between the two until the lower or bearing pivot is unseated. Theinner edge of the framework is also recessed at 25, in order tofacilitate the grasping of the cards or other objects which are to bedisplayed. For the reception and securing of these cards, the threeexposed edges of the frame are provided with flanges 27, attached to theframe and with their overlapping edges projecting a short distancerearwardly with interposition of a sufficient space to receive a card ofthe thickness which it is proposed to display upon the leaf. On theinner edge marginal strips 28, are similarly mounted. By thisarrangement Whenever a leaf is removed from the stand, two cards 29, 29,may be slid beneath the margins 28, and under the flanges of the otherledges, and thus be secured one on either side of the swinging leaf forpurposes of display. In operation when cards, sheets, time-tables,

photographs or other objects are mounted upon the leaves, the latter areall secured within their bearings in the shelves and so remain underlock and key until one rovided with the key unlocks the locking s elfand by removin one or more of the leaves slips out the car s or otherdisplayed objects and replaces them with others. It is obvious thatexcept whenthus removed, the displayed cards are fixedly held withintheir mountings on the leaf and cannot be wrongfully removed.

If desired, a protecting sheet of glass or celluloid 29 may be slippedwith the card into the frame.

Having thus described my invention, I claim:- 7

1. A display device comprising rectangular leaves, fixed pivotalbearings coincident with one of their edges, a stand for mounting saidleaves consisting of two horizontal spaced ledges, the lower led e beingprovided with socket bearings for the lower ends of the pivots, and theupper ledge being provided with corresponding bearing holes- 2. Adisplay device comprising one or more rectangular display leaves withpiv-,

otal bearings coincident with one of the edges thereof, two horizontalledges suitably spaced; sockets in the lowermost ledge; vertical bearingholes in the upper ledge with beveled enlargements which permit theinclination of the pivotal bearings within bearing holes prior to theirremoval.

In testimony whereof, I have hereunto signed my name, at Philadelphia,Pennsylvania, thistwenty-fourthday of April 1908.

ALFRED M. PARKS.
